A string is warapped around a cylinder of mass m and radius r. The string is also connected to a block of same mass m with the help of another pulley as shown in figure. The angular acceleration of the cylinder is ( friction is sufficient for rolling ) ( all pulleys are ideal)

The block of mass m is at rest. Find the tension in the string A .

A string is wrapped several times on a cylinder of mass M and radius R . the cylinder is pivoted about its adxis of block symmetry. A block of mass m tied to the string rest on a support positioned so that the string has no slack. The block is carefully lifted vertically a distance h , and the support is removed as shown figure. a. just before the string becomes taut evalute the angular velocity omega_(0) of the cylinder ,the speed v_(0) of the falling body, m and the kinetic energy K_(0) of the system. b. Evaluate the corresponding quanitities omega_(1), v_(1) and K_(1) for the instant just after the string becomes taut. c. Why is K_(1) less than K_(0) ? Where does the energy go? d. If M=m , what fraction of the kinetic energy is lost when the string becomes taut?

One end of a string is tied to a rigid support attached to roof and the other end is wound around a uniform wheel of radius r and mass m. The string is kept vertical and the wheel is released from rest. As the wheel descends show that (i) the tension in the string is one-third the weight of the wheel, (ii) the magnitude of the acceleration of the centre of mass is 2g/3 and (iii) the speed of the centre of mass is (4gh//3)^(1//2)

A string is wound around a hollow cylinder of mass 5 Kg and radius 0.5 m. If the string is now pulled with a horizontal force of 40 N, the cylinder is rolling without slipping on a horizontal surface (see figure), then the angular acceleration of the cylinder will be (Neglect the mass and thickness of the string).

One end of a massless string is wound around a cylinder of mass 5 kg and radius 16' cm. The cylinder' is mounted symmetrically on a horizontal axle so 5 that It can freely rotate about its axis, to the other end of the string a mass of 500 gm is attached. Calculate the acceleration of the mass when it is released from rest.

On the surface of a solid cylinder of mass 2 kg and radius 25 cm a string is wound several times and the end of the string is held stationary while the cylinder is released from rest. What is the acceleration of the cylinder and the tension in the string ?

A massless string is wrapped around a hollow cylinder having mass m and radius r . The cylinder is kept on a rough horizontal surface (coefficient of friction is mu ). A constant force F is applied as shown in the figure. In case of pure rolling, the friction force acting on the bottom most point of the cylinder is

The string of a pendulum is horizontal. The mass of the bob is m. Now the string is released. The tension in the string in the lowest position is -

Consider the arrangement shown in figure. The string is wrapped around a uniform cylinder which rolls without slipping. The other end of the string is passed over a masslessm frictionless pulley to a falling weight, determine the acceleration of the falling mass m in terms of only the mass of the cylinder M , the mass m and g
